IPO Basis of Allotment

Basis of Allotment (or Basis of IPO Stock Allocation) is a document published by the registrar of an IPO after finalizing the share allocation based on SEBI guidelines. This document provides information about the demand of the IPO stock.

The IPO allotment information is categorized by number of shares applied by investors. For each such category detail bidding information is provided in this document including number of valid application received, total number of share applied, ratio of the allotment and number of shares allocated to the applicants.

Ratio of the allotment is a critical factor for IPO's oversubscribed multiple times. This field tells how many applicants will receive single lot of shares among a certain number of applicants. For example, ratio 1:8 means only one out of eight applicant received one lot of shares; ratio value 'FIRM' means all the applicants are eligible to receive certain amount of share.
